pnmtosgi - convert a portable anymap to a SGI image file
SYNOPSIS
pnmtosgi [-verbatim|-rle] [-imagename Name] [pnmfile]
DESCRIPTION
Reads a portable anymap as input. Produces an SGI image file as output. The SGI image will be 2-dimensional (1 channel) for PBM and PGM
input, and 3-dimensional (3 channels) for PPM.
OPTIONS -verbatim
Write an uncompressed file.
-rle (default)
Write a compressed (run length encoded) file.
-imagename name
Write the string "name" into the imagename field of the header. The name string is limited to 79 characters. If no name is given,
pnmtosgi writes "no name" into this field.
BUGS
Probably.

ppmtopcx - convert a portable pixmap into a PCX file
SYNOPSIS
ppmtopcx [-24bit] [-packed] [-xpos=cols] [-ypos=rows] [ppmfile]
DESCRIPTION
Reads a PPM image as input. Produces a PCX file as output. The type of the PCX file depends on the number of colors in the pixmap:
16 colors or less:
1 bit/pixel, 1-4 planes.
256 colors or less:
8 bits/pixel, 1 plane, colormap at the end of the file.
More than 256 colors:
24bit truecolor file (8 bits/pixel, 3 planes).
OPTIONS -24bit Produce a 24bit truecolor file, even if the pixmap has 256 colors or less.
-packed
Use "packed pixel" format for files with 16 colors or less: 1, 2, or 4 bits/pixel, 1 plane.
-xpos=cols
-ypos=rows
These options set the position of the image in some field (e.g. on a screen) in columns to the right of the left edge and rows below
the top edge. The PCX format contains image position information. Don't confuse this with the position of an area of interest
within the image. For example, using pnmpad to add a 10 pixel left border to an image and then converting that image to PCX with
xpos = 0 is not the same as converting the original image to PCX and setting xpos = 10.
The values may be from -32767 to 32768.
The default for each is zero.

Hi,
What is installation package and how to create it?
When we run:

What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
